Title: Improvements in or relating to cathode ray tubes
IPC: H01J29/62
Filed: 1933-05-12
Abstract: 421,050. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. May 12, 1933, Nos. 13842 and 13843. Convention dates, May 14, 1932 and July 15, 1932. [Class 39 (i)] In a cathode - ray tube of the gas-filled or high-vacuum type and with a cathode, an anode, a fluorescent screen and deflecting devices for scanning the screen, a non-uniform electrostatic field concentrating the electrons between the cathode and the screen is produced by an electrode spaced from the wall of the tube and of semiconductive material with a potential difference applied across its extremities. A semi-conductive coating on the side of an apertured mica disc 1, Fig. 2, facing the anode 7 may be connected at its inner circumference to the preliminary anode 11 and at its outer circumference to a more negative variable potential to produce between the disc 1 and the anode 7 an inwardly directed field of intensity increasing away from the axis of the tube. The coating on the disc 1 may be non-uniform. Metal screens 6, 8 have the same potential as the anode 11. Further concentrating means may be provided. A Wehnelt cylinder 9 may concentrate and control the electrons leaving the cathode 10. In a modification, Fig. 3, the concentrating electrode 15 between the cathode 10 and anode 7 is tubular with apertured end plates and is of diameter decreasing along its axis in the direction of motion of the electrons. A converging accelerating field is produced inside the electrode 15 by applying a potential difference across the semi-conductive material on its surface. The concentrating electrode may be a carbon coating on insulating material or a mass of aluminium or other insulating oxide mixed with carbon.

Title: Pre-set glow transfer counter
IPC: H03K29/00
Filed: 1955-05-13
Abstract: 786,903. Electronic counting - apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 13, 1955 [May 17, 1954], No. 13872/55. Class 106 (1). An electronic counting device for predetermined counting comprises for each denomination an N-state counter associated with an N-position manually settable switch, and means are provided for pre-setting the device to a state representative of the sum of the (N-1), complement of a number registered on the switches and unity. As described, N has the value ten, each denominational counter is a multi - cathode thermionic tube, and the device is said to be for counting batches of printed cards, each card being produced in synchronism with a complete cycle of cams C1-C4, Figs. 1 and 2. In operation a number, for example 2850, as shown, is registered on a bank of control switches, Fig. 4, a reset switch 26 is depressed, causing the tens complement (nines complement plus unity) of the registered number to be set up in the device, and then after the registered number of cycles of input pulse cam C1, Fig. 2, the highest order denominational counter produces an output signal which energizes a magnet M for controlling some mechanism associated with the card printer, and which also causes the tens complement of the number registered on the switches to be re-entered into the counting device for counting a second batch. Each control switch, for Example S2, Fig. 2, comprises three ganged sections X, Y and Z shown registering 5. For the lowest order switch S1, the X-section is not used and for the highest order switch S4 the Z-section is not used. Upon depression of the set-up switch 26, the hold coil of a relay F, Fig. 1, is energized, closing contacts F1, F2, F3, F4, and causing the voltages of those cathodes that correspond to the tens complement of the number registered on the switches to be lowered from 135 v. to earth level, thus setting up the required number. As shown, since zero is registered on switch S1, relay Wl will be energized (terminal 33, Z-section of switch S1 and lead 34) and the tens counter will be set in accordance with the Y-section of switch S2. Relay W1 and the other similar relays for the higher order counter can be regarded as effecting inter-denominational carry as a result of the addition of unity to the nines complement. Inter-denominational carry is effected during counting by transformers PT1, &c. When the counting device has received the appropriate number or input pulses from cam C1, a carry output pulse from the highest denomination fires a thyratron E5, energizing the magnet M and the relay F and thus re-entering the tens complement of the number registered on the switches for counting a second batch. Specification 720,179 is referred to.

Title: Improvements in or relating to the Breech Mechanism of Ordnance.
Inventor: ASBURY DORSEY FROST
IPC: F41A5/32
Filed: 1916-10-02
Abstract: 101,716. Asbury, D. F. Oct. 4, 1915, [Convention date]. Ordnance breech mechanism. - Relates to poweroperated screw breech mechanism of the kind having a brake device comprising a reciprocating-element which moves constantly with the breech-actuating motor to control the movements of the breech mechanism, and is par ticularly applicable to the mechanism described in Specification 16406/15. According to the present invention, the breech-actuating motor comprises a reciprocatory-element which is rigidly connected to and moves with the reciprocatorv-element of the brake device during its entire stroke. Fig. 1 shows a rear view of the breech with the screw in the closed and locked position. The breech is actuated by an air-pressure cylinder-and-piston device, the cylinder 33 of which is hinged to the gun, the piston 48 being, by means of its rod 34, connected to an arm 25 fixed to the upper end of a shaft 14. This shaft rotates in the breech-screw carrier C and, through the medium of a crank 15, pin 16, and sliding block 20, moves a link to rotate the breech-screw for locking and unlocking. When the breech-screw is rotated for unlocking, camdevices M, N initiate the opening movement of the carrier, and the further movement of the piston 48 then causes the carrier to swing open. The hydraulic brake device for controlling the movements of the breech mechanism has its cylinder 34 mounted within the pneumatic cylinder 33 so as to form a guide for the piston-rod 46, to which are connected the brake piston and rod 52, 51. The brake cylinder is kept full of liquid by providing a reservoir 36 which communicates with the brake by a ball valve 40. The reservoir 36 is filled through an opening provided with a screwed plug 42 having a central portion 43 forming an air-pocket, the end portion of the plug being formed with openings 44, 45. Leakage of liquid is thereby prevented, and atmospheric pressure is maintained above the surface of the liquid in the reservoir. During the breech-opening movement, the liquid flows freely through a by-pass 54 and ball valve 55 until the by-pass moves beyond a flange 56, when throttling occurs between the piston 52 and a reduced portion of the cylinder to bring the carrier to rest gently in the open position. The space 58 being in communication with the low-pressure side of the piston, the packing 53, where the piston-rod leaves the cylinder, is not subjected to the braking-pressure. When the breech-closing movement occurs, the valve 55 closes, and a variable braking occurs between the piston 52 and portions of the cylinder 34 of different diameters and also by liquid passing through a passage 38 into the reservoir.

Abstract: 482,793. Cycles ; oil engines. HEYLANDT, C. W. P. May 22, 1937, Nos. 14307, 14308, and 14310. Convention dates, May 22, 1936, May 30, 1936, and July 24, 1936. [Classes 7 (ii) and 7 (iii)] In a method of operation in which heat derived from the cooling water or exhaust gases or both is used to vaporize water or another inert medium, the steam &c. is introduced during the compression stroke after the closure of the inlet valve, is compressed and after the ignition expanded with the combustion products in two stages down to atmospheric pressure, the combustion products doing external work during the expansion. The inert medium may be compressed together with either combustible mixture or combustion air, the combustible then being introduced at the end of the stroke. The combustion gases are exhausted at the final pressure of the expansion stroke into a second working chamber, which may be a rotary piston engine, and the chambers are freely connected together to permit the exhaust and expansion to take place simultaneously, the pressure finally dropping to about one atmosphere. To avoid excessive heat in the second working chamber, the inert medium may be superheated by the gases passing to the second chamber to reduce their temperature to about 600‹ C. Alternatively compressed air may be introduced into the cylinder at or after the end of the working stroke and pass with the gases into the second chamber. The Specification as open to inspection under Sect. 91 states that (1) the steam may be heated to above 300‹ C., and be introduced at a pressure of more than three atmospheres during or after the working stroke ; (2) steam at a pressure of from 2-3 atmospheres may be introduced during the suction stroke to inject the charge into the cylinder, and (3) in Diesel engines an inert gas may blow into the cylinder an easily ignitable fuel, too rapid ignition being thus avoided. This subjectmatter does not appear in the Specification as accepted.
